This are all the answers for Potential Energy of a System Quick Check for Connexus students.
Q1: Use the picture to answer the question. The girl in the picture is at the highest point in swinging and starts to come down. Which statement could describe the changes in energy for her?
Kinetic energy is increasing, and potential energy is decreasing.

Q2:Earth is closest to the sun around January 3 each year, and it is farthest from the sun near July 4. Around which date would Earth be moving the slowest as it orbits the sun?
July 4

Q3: Use the picture to answer the question. At which of the three points, if any, is the bicyclist’s potential energy increasing?
The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.

Q4: How would potential energy and kinetic energy change going down stairs one at a time or two at a time?
If you go down stairs two at a time, then your potential energy relative to the stair is greater. Your kinetic energy will be greater when you land.
